The MW3 ladder is actually messed up in the head if it had one. It doesn't roll over on time, it rolls over at different times for different teams, effectively rendering some teams useless of challenging a particular team compared to another. For instance, why did Reign roll over straight up after beating viraL, but we (Empire) didn't roll over straight up after beating Cortex? We had plans to challenge a team but we couldn't do that because we're still stuck in a challenge from Cortex an hour after it's meant to roll over.

So here is another question, if this happens tomorrow night, where teams should have the 29 minute gap of challenging between the supposed roll over time and ladder lock, if no team can challenge because of the glitch, will the ladder lock be extended however long it took to roll over?

It needs to pull it's finger out to be honest.

We wanted to challenge Crux Crew but it rolled over late for us. It's just something you have to deal with and is nothing the adminds can fix. I believe it's a server issue.

If an admin wishes to answer the second question they will, otherwise everyone has heard the complaining before.

~Locked.

I have been refreshing for 1 hour and 15 minutes, waiting for Excision to be vulnerable.

Like Lord says it isn't something that can be fixed easily.

We are all in the same boat

Sorry for posting after the lock, BUT:

@Bundo, if you check out the MW3 S&D schedule you'll notice that ladder lock isn't until 1-2am Wednesday morning/Tuesday night (however you like to think of it), as opposed to midnight. Pretty sure that is done to cater for the ladder ticking over late, because in CGo S1 Black Ops the exact same problem occurred.
Generally it's only an hour late max, so everyone should be able to get challenges off before the ladder locks.
